With GCam Tool 2.0, all photos (even panorama and photosphere) are moved automatically in the background. If you want to save portrait mode photos into a different folder, this must be the easiest way.
Another request I got was regarding the way Google Camera took selfies. Most OEM camera apps give you the option to save the front camera image just like you see in camera preview. Strangely Google Camera doesn't allow this and always saves the image flipped. With v2.0, GCam Tool can now detect front camera photos and prevent it from being flipped.
I must give the disclaimer that this is an experimental feature. Google doesn't provide any sort of API for developers to detect whether a photo was taken with front or back camera. I had to come up with my own method of detecting that. I tested on S8+, OnePlus 3 and Redmi Note 4 and it worked fine. If this feature fails on your phone, please let me know the device model as well as the Android version.
Please try the app and let me know your feedback. If you like it, please take a moment to rate and review on Play Store.
